Fuel pressure is at 67 psi @ idle. A friend said it looked high. Fuel system consist of a Walbro GSS342 pump, ID725's, dyno tune's fuel pressure gauge adapter (like the AAM) and a direct reading gauge (autometer) Other than that its the stock returnless system.

Had it tuned and drives fine.. Just wondering. Any input?

 

Is there another mod that needs to be done other than trimming the tabs off on the pump base inself? I followed a thread on the install of the pump to the "T", but I read elsewhere today about a fuel pump hanger mod to achieve proper flow, but searchng for that mod it brings up return systems. Heres what Injected Performance states on there listing for the pump;

"Your factory fuel pump hangar will require minor modification to achieve the correct fuel flow"

 

Looks like I may have missed a few steps? This is what I found;

yup

 

The particular thread I followed did not include those steps. So simple...

Just waiting on a .070 drill bit. (AKA #50) Should be here by Thursday. Then another 3 hour trip to the tuner...

Just the way it goes I guess.
